make and use the same, reference being had to the accompanying drawings, forming part The object of my invention is to provide a journal bearing for railway cars which will be simple in' construction and in which the bearing, metal will be so disposed that the greatest possible amount of wear can be secured from the same and also to so construct the bearing that the parts will be interchangeable with the standard M. C. B. type of hearing.

In theaccompanying drawings which illustrate some forms of journal bearing made in accordance with my invention, Figure 1 is a vertical central section through the oil box of the car to which my journal bearing is applied; Fig. 2 is an enlarged cross-section of the brass and wedge; Fig. 3 is a cross-section of the brass showing a slight modification; Fig. 4 is a top view ofv the form of brass shown in Fig. 3; Figs. 5 and 6 are views similar to Figs. 3 and 4 but showing a still further modification; Fig. 7 is a rear end view of the brass; Fig. 8 1s a section on the line 88 of Fig. 6; Fig. 9 is a top plan view of the brass shown in Figs. 1 and 2; Fig. 10 is a top plan view partly in section of the wedge; Fig. '11 is an end view of thewedge shown in Fig. 10, and Fig. 12 is a view similar to Fig. 10 but showing a sli ht modification.

ike marks of reference refer to similar parts in the several views of the drawings. 15 represents the oil box of the car and 16 the axle. The oil box 15 is provided with the usual hinged cover 17 and with a lug 18 projecting downwardly from the upper portion to engage with the wedge, as will be hereinafter more fully described. The axle 16 is provided with the usual bearing portion 19 and with the collar 20. Engaging with thebearing portion 19 is the brass 25. This brass 25 may be made entirely of bearing metal as shown in Figs. 1 and 2 and provided with the usual lining of soft metal 26 to facilitate its fitting to the axle 19. The

brass 25 is provided with the usual laterally projecting lugs 27 for engaging with the oil box 15- and these projections 27 are provided with squared forward ends 28 for engaging with projections on the wedge-as will be hereinafter described. The upper face of the brass 25 is formed of alternate ribs29 and depressions 30, as best shownin Fig. 9. The ribs 29 conform to the under face of the wedge and the depressions 30 are curved on the arc of a circle. of substantially the same radius as the under face of the bearing 25, as is best seen in Fig. 2. In this way the greatest possible amount of wear is obtained from the bearing metal in the brass.

In Figs. 3 and 4 I have shown a modification in which the brass is not made ontirely of bearing metal. In this form of bearing the back of the brass may be made of cast iron or other suitable metal, while only the lining 31 is formed of bearing metal. This lining 31 is secured in position by means of lugs 32 which pass through.

openings in the back of the brass and into the spaces between the ribs 29. The in The upper face of the lining 31 is curved on the arc of a circle of substantially the same radius as the lower face of the lining and the depressions 30. V

In Figs. 5 and 6 I have shown a still further modification in which the lining 31 is provided with lugs 33-which extend up flush with the ribs 29 and are secured in position by means of rods 34 passing longitudinally through the ribs 29 and the rods 34 are riveted as shown at 35. The rear end of the brass 25 projects beyond the wedge, as is shown in Fig. 1, and the upper face of this rear end is flush with the top of the ribs 29.- At the sides, however, projections 36 are provided for engagin with the wedge when the standard form 0 M. C. B. wedge is used. In this way the wedge is made interchangeable with the standard wedge and at the same time the wedge and brass are readily detached from the box. The wedge 40 in place of being made solid is hollow, all the walls bein of substantially the same thickness. T e upper and lower walls of the wedge are connected by means of integral webs41, these webs being of substantially the same thickness as the walls of the wedge. In this way the entire wedge can be annealed and thus a from the wedge.

jections 27 on the brass.

very strongwedge is obtained with the minimum amount of metal. The core usedin forming the hollow wedge may be removed through openings 42 for the core prints. In Fig. 12, however, I have shown a modification in which the core is not removed which fuse into the metal when the wedge is cast and the ends of which may be removed after the wedge has been formed, thus leaving the sand of the core in position in ,the wedge. I have found that in this way I can overcome the expense of removing the core from the wedge and that the sand in the wedge does not interfere with the proper annealing of the walls thereof. Projecting from the forward part of the wedge 40 are wings 44 adapted to engage with the lugs 18 on the box 15 and thus prevent the forward movement of the wedge. These wings 44 are continued downwardly into the projections 45 adapted to engage with the forward square ends 2-8 of the'pro- The wings 44 with their extensions 45 are so arranged as to clear the collar 20 on the axle 16. The collar 20 is likely to wear some distance into the brass 25' and thuswould come into contact with the metal of the parts 44 and 45 if they were not arranged as above stated.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a journal bearing for cars, the combination with a journal, of a wedge having an angular under face, a brass having a part of its upper face conforming to the under face of the wedge, and another part;

thereof curved to conform to the periphery of the journal, the angular part of the upper face of said brass contacting with the lower face of said wedge, and the highest In this modificationv the core 1s supported by means of wires 43 roaaeoo point of the curved part of the upper face of said brass also contacting with the lower face of the wedge.

2. In a journal bearing for cars, the combination with a wedge having an angular.

under face, of a brass the back of which comprises alternate ribs and depressions, a lining for said brass, and lugs carried by said lining and having their ends projecting through said brass into the recesses between the ribs, said projecting ends being provided with releasable retaining means for holding the lining in position against the brass.

3. In a journal bearing for cars, the combination with a wedge having an angular under face, of a brass the back of which comprises alternate ribs and depressions, the ribs conforming to the under angular face of the wedge and the depressions being curved, a lining for said brass having lugs extending through said brass into spaces between the ribs, and rods passing through said lugs and ribs to secure the lining in position.

4. In a journal bearing'for cars, the combination with a wedge having an angular under face, of a brass the back of which comprises alternate ribs and depressions, the ribs conforming to the under angular face of the wedge and the depressions conforming to an arc of substantially the same radius as the under face of the brass, a lining for said brass having lugs extending through said brass into the spaces between the ribs, and rods passing through said lugs and ribs to secure the lining in position.

In testimony whereof I have hereunto set my hand and affixed my seal in the presence 'of the two subscribing witnesses.
